The cuisine that comes to mind when I think of spicy food is Korean. Koreans basically eat something spicy every meal in the form of kimchi, and sometimes eat extremely spicy meals. I've heard that basically all Koreans have at least mild stomach inflammation because of this. Koreans also eat quite a lot of meat, using the spiciness of kimchi to clean their palate. I wonder if the health effects can be seen in the Korean population, or if the probiotics in the kimchi will confound the results.
